SPARQL

Define a Lua module that requires the SPARQL binding and uses its runQuery method.

Example:

Create page Module:MySPARQL

local sparql = require('SPARQL') -- Load the SPARQL binding

local p = {}

function p.showFirstValue(frame)
  local sparqlQuery = frame.args[1]
  local queryResults = sparql.runQuery(sparqlQuery) -- Use the runQuery method

  local firstColName = queryResults['head']['vars'][0]
  return queryResults['results']['bindings'][0][firstColName]['value']
end

return p

Which can then be invoked via Scribunto's normal mechanisms from within wikitext.

Example:

{{#invoke:MySPARQL|showFirstValue|your SPARQL query here}}

Lua module Examples:

• Show the first value (README example)
• Show everything
• Build an HTML table
